Boeing Starliner Spacecraft 2
Boeing Starliner Spacecraft 2 is the first of two active Boeing CST-100 Starliner spacecraft developed and built under NASA's Commercial Crew Program. The spacecraft was originally scheduled to make its maiden flight on Boe-CFT, the first crewed flight test of the Starliner spacecraft, although following the partial failure of the other CST-100 on Boe-OFT which required a repeat uncrewed test ( Boe-OFT-2) of the spacecraft to be scheduled, spacecraft 2 was reassigned to Boe-OFT-2 and also scheduled to fly Starliner-1 after being reassigned from CFT mission. History In September 2014 Boeing was one of two companies selected by NASA to develop crewed spacecraft to ferry astronauts to the International Space Station, the other being SpaceX. Boeing planned to construct three Starliner spacecraft. The spacecraft's ability to be reused up to ten times with a six-month turnaround time between flights meant three spacecraft would be enough to satisfy the needs of the Commercial C ...

Boeing Orbital Flight Test
The Boeing Starliner Orbital Flight Test (also known as Boe-OFT) was the first orbital mission of the CST-100 Starliner spacecraft, conducted by Boeing as part of NASA's Commercial Crew Program. The mission was planned to be an eight-day test flight of the spacecraft, involving a rendezvous and docking with the International Space Station (ISS), and a landing in the western United States. The mission was launched on 20 December 2019 at 11:36:43 UTC or 06:36:43 AM EST; however an issue with the spacecraft's Mission Elapsed Time (MET) clock occurred 31 minutes into flight. This anomaly caused the spacecraft to burn into an incorrect orbit, preventing a rendezvous with the International Space Station (ISS). The mission was reduced to just two days, with the spacecraft successfully landing at White Sands Space Harbor on 22 December 2019. On 6 April 2020, Boeing announced that it would conduct another Orbital Flight Test to prove and meet all of the test objectives. NASA accepte ...

Falcon 9
Falcon 9 is a partially reusable medium lift launch vehicle that can carry cargo and crew into Earth orbit, produced by American aerospace company SpaceX. The rocket has two stages. The first (booster) stage carries the second stage and payload to a certain altitude, after which the second stage lifts the payload to its ultimate destination. The rocket evolved through several versions. V1.0 flew from 2010–2013, V1.1 flew from 2013–2016, while V1.2 Full Thrust first launched in 2015, encompassing the Block 5 variant, flying since May 2018. The booster is capable of landing vertically to facilitate reuse. This feat was first achieved on flight 20 in December 2015. Since then, SpaceX has successfully landed boosters over 100 times. Individual boosters have flown as many as 15 flights. Both stages are powered by SpaceX Merlin engines, using cryogenic liquid oxygen and rocket-grade kerosene (RP-1) as propellants. The heaviest payloads flown to geostationary transfer o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta IV
Delta IV is a group of five expendable launch systems in the Delta rocket family introduced in the early 2000s. Originally designed by Boeing's Defense, Space and Security division for the Evolved Expendable Launch Vehicle (EELV) program, the Delta IV became a United Launch Alliance (ULA) product in 2006. The Delta IV is primarily a launch vehicle for United States Air Force (USAF) military payloads, but has also been used to launch a number of United States government non-military payloads and a single commercial satellite. The Delta IV originally had two main versions which allowed the family to cover a range of payload sizes and masses: the retired Medium (which had four configurations) and Heavy. As of 2019, only the Heavy remains active, with payloads that would previously fly on Medium moving to either the existing Atlas V or the forthcoming Vulcan. Retirement of the Delta IV is anticipated in 2024. , two flights remain. Delta IV vehicles are built in the ULA facility ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Escape System
A launch escape system (LES) or launch abort system (LAS) is a crew-safety system connected to a space capsule that can be used to quickly separate the capsule from its launch vehicle in case of an emergency requiring the abort of the launch, such as an impending explosion. The LES is typically controlled by a combination of automatic rocket failure detection, and a manual activation for the crew commander's use. The LES may be used while the launch vehicle is still on the launch pad, or during its ascent. Such systems are usually of two types: *A solid-fueled rocket, mounted above the capsule on a tower, which delivers a relatively large thrust for a brief period of time to send the capsule a safe distance away from the launch vehicle, at which point the capsule's parachute recovery system can be used for a safe landing on ground or water. The tower and rocket are jettisoned from the space vehicle in a normal flight at the point where it is either no longer needed, or cannot be e ...

Hypergolic Propellant
A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other. The two propellant components usually consist of a fuel and an oxidizer. The main advantages of hypergolic propellants are that they can be stored as liquids at room temperature and that engines which are powered by them are easy to ignite reliably and repeatedly. Common hypergolic propellants are difficult to handle due to their extreme toxicity and/or corrosiveness. In contemporary usage, the terms "hypergol" and "hypergolic propellant" usually mean the most common such propellant combination: dinitrogen tetroxide plus hydrazine and/or its relatives monomethylhydrazine (MMH) and unsymmetrical dimethylhydrazine (UDMH). History In 1935, Hellmuth Walter discovered that hydrazine hydrate was hypergolic with high-test peroxide of 80-83%. He was probably the first to discover this phenomenon, and set to work ...

RS-88
The RS-88 is a liquid-fueled rocket engine burning ethanol as fuel, and using liquid oxygen (LOX) as the oxidizer. It was designed and built by Rocketdyne, originally for the NASA Bantam System Technology program (1997). In 2003, it was designated by Lockheed for their pad abort demonstration (PAD) vehicle. NASA tested the RS-88 in a series of 14 hot-fire tests, resulting in 55 seconds of successful engine operation in November and December 2003. The RS-88 engine proved to be capable of of thrust at sea level. A hypergolic derivative of the RS-88 has been selected for the Boeing CST-100 Starliner launch escape system. This version is capable of 39,700lbf (176.6kN) of thrust and four are used in Starliner's abort system. Bantam Launch System The Bantam System Technology Project, which is part of the Low Cost Technologies effort, teams NASA and its business partners to research and demonstrate technologies for a new low-cost launch system.

Heat Shield
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA Docking System
The NASA Docking System (NDS) is a spacecraft docking and berthing mechanism used on the International Space Station (ISS), the Orion spacecraft, and the Starliner. The NDS is NASA's implementation of the International Docking System Standard (IDSS), an international spacecraft docking standard promulgated by the International Space Station Multilateral Coordination Board. The international Low Impact Docking System (iLIDS) is the precursor to the NDS. NDS Block 1 was designed and built by The Boeing Company in Houston, TX, to meet the IDSS standards. Design qualification testing took place through January 2017. Using NDS, NASA developed the International Docking Adapter (IDA) to provide two IDSS-compliant docking ports on the ISS. The IDAs were delivered to the ISS starting in 2016. Each of two existing Pressurized Mating Adapters has an IDA permanently attached, so the former PMA function is no longer available for visiting spacecraft. Since 2019, visiting spacecraft dock to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
